Recently, I finally got to ride (if that is the right word) a Segway two-wheeler. Quite fun, actually. But when thinking hard about it, it really seems like a pretty pointless invention. Cool technology, fantastic control system design and programming – but still, it does not solve any real problem. As a product manager, my mind tends to view new things with an eye toward “what is the problem they are trying to solve” rather than how fun, attractive, or well-designed they are. Sometimes, good design is the point, of course. However, in this case, we are talking about a transportation device, and as such, the question is where it fits.
At the ISCA 2014 conference (the biggest event in computer architecture research), a group of researchers from Microsoft Research presented a paper on their Catapult system. The full title of the paper is “A Reconfigurable Fabric for Accelerating Large-Scale Datacenter Services“, and it is about using FPGAs to accelerate search engine queries at datacenter scale. It has 23 authors, which is probably the most I have ever seen on an interesting paper. There are many things to be learnt from and discussed about this paper, and here are my thoughts on it.
